在口语交流中,我们可以这样描述这个特性:“In C++, we can use thedeletekeyword to prevent object moving. By marking the move constructor and move assignment operator asdelete, we can ensure that objects of the class cannot be moved. If we try to move an object, the compiler will throw an er...

constructor 将Test(Test&& test) = delete修改为Test(Test&& test) = default或者显式定义虽可以修复此问题,然而,之前的本意就是将移动构造删除,让其使用拷贝构造啊,如此修改违背了本意。 更进一步的观察,竟然未输出move constructor!重载决议选择了移动构造,但未执行移动构造,有点反直觉,此问题请参考尾返回值优化...
